To (all whom, it may concern:

3 Be it known that I, GEORGE F. STEEDMAN, a citizen of the United States, residing at St. Louis, Missouri, have invented a certain new and useful Improvement in Elevators, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a front elevation of a directtype elevator embodying the features of my invention. Fig. 2 is a detail view, partly in section, showing the inner face of the righthand side standard of the elevator-frame. FigL s a StlOD2Ll., QW.QI -th8 line 3 3 of Fig. 2, and Fig. 4 is a sectional view on the line 4 4 of Fig. 2.

This invention relates to stationary elevators, and particularly to that class of elevators operated by a fluid-actuated hoist where the lineal motion of a piston in a cylinder is directly transmitted to the cage by medium of ropes and sheaves or direct con nection of the piston-rod to the cage, as shown in the accompanying drawings, the term stationary elevators being used to indicate those elevators which are rigidly connected to the framing or walls of a building and forming part of the building.

The object of my invention is to incorporate all of the necessary parts of such an elevator into a self-contained machine wherein all of the operating parts are carried by the framework of the elevator, enabling me to assemble the complete elevator at my factory, disassemble or knockdown same, and ship it to a distant customer in such form that the customer may again assemble the machine complete at the place where it is to be permanently located.

Prior to my invention it has been the practice to build the frame of a stationary elevator at the place where the elevator was installed, so that the manufacturer was obliged to send an experienced elevator-man to said place, and considerable time was expended in the erection of the elevator, because the workman was usually obliged to build the frame with hand-tools and attach the component parts to surrounding parts of the building or provide special means for carrying the component parts, so that the cost of manufacture of the elevator was greatly enhanced.

My improved elevator is constructed complete with frame at the factory, thus enabling machine-tools to be used, which reduces greatly the cost of manufacture, and the elevator is then shipped to theplacewhere the elevator is to beinstalled. The frame comprises very few partsnamely, two side standards and cross members which are connected to the side standards by castings, which insures a very rigid construction, the castings at the upper portion of the frame cooperating with buffers on the elevator-cage and the castings at the lower portion of the frame being provided with buffers which cooperate with surfaces on the lower part of the cage;

In Fig. 1 of the drawings, which illustrates a direct-type elevator, the side standards are designated by the numerals 1, saidstandards having castings 2, secured to their upper ends by means of bolts 3. Mounted on the up er faces of said castings are cross-beams 4, t at are secured thereto by bolts 5, thus rigidly connecting said beams and side standards together. Castings 6 are connected to the lower ends of the side standards and act as foundation-plates to insure a firm foundation for the elevator-frame. Guides 7 are connected to the side standards for the elevatorcage 8 to travel on, and the hoisting device 9 for saidcage is removably connected by bolts 10 to the upper cross-beams.

As the hoisting device forms no part of my present invention, I have not deemed it' necessary to describe the same nor the mechanism for controlling the operation of said hoisting device, which mechanism is designated 'by the reference-numeral 11 and is carried by a support in the form of angleirons 12, that are connected to the right-hand side standards by means of brackets 13.

In the direct-type elevatortwo counterweights 14 are employed, which travel on tracks 15, secured to the side standards by devices 16, the sheaves 17 for said counterweights being mounted in the upper crossbeams. It will be noted that in this type of elevator the angle-irons 12, which carry the hoist-controlling mechanism, are located some distance from the side standard to provide a passage-way for the counterweight, as shown clearly in Fig. 3. As previously mentioned, each of the upper castings has a surface 17 which cooperates with a buffer 18 on the elevator-cage, and the lower castings carry buffers 19, which cooperate with en gaging faces on the bottom of the cage.

From the foregoing description it will be seen that I have provided an elevator-frame comprising very few parts, which can be con' structed and assembled at the factory, disassembled, and shipped on a car to the point where the elevator is to be installed, the frame having no upwardly-projecting portions when the angle-irons 12 are removed, so that it occupies but very little space and accordingly can be shipped at a low freight classification. Furthermore, as it is not necessary to employ a skilled mechanic to set up the elevator the cost of erecting the same is greatly reduced. When the frame is set up and all parts reassembled, it is only necessary to attach some simple braces to the upper portion ofthe frame extending to the ground or nearby structure to secure rigidity V of the frame.

bers, castings secured to the upper ends of 1 said members and projecting beyond the inner sides thereof to constitute buffing-surfaces, cross members spaced away from each other and mounted on the upper ends of said castings, means for fastening said cross members to said castings, foundation-castings secured to the lower ends of the upright members, a cage arranged between said upright members,a pneumatic hoisting mechanism secured to said cross members, a transverselyeXtending member fastened to one of the upright members, and means carried by said transversely-extending member, for controlling the pneumatic hoisting mechanism.

2. A knockdown elevator comprising a frame which consists of two vertical members, castings secured to the upper ends of said members and projecting beyond the sides thereof to constitute buffing-surfaces, cross members spaced away from each other and mounted on the upper ends of said castings, means for fastening said cross membersto said castings, foundation-castings secured to the lower ends of the vertical members, buffers mounted on said foundation-castings, a cage arranged between said vertical members and provided at its upper end with buffers, a pneumatic hoisting mechanism arranged between said cross members and connected thereto, a transversely extending member secured to one of the vertical members, means carried by said transversely-extending member for controlling the pneumatic hoisting mechanism, tracks fastened to the outer sides of the vertical members, counterweights traveling on said tracks and connected to the cage by cables and sheaves journaled on the cross members over which said sheaves travel.

3. A knockdown elevator, comprising a frame which consists of two upright members, castings secured to the upper ends of said members, cross members spaced away from.

each other and mounted on the upper ends of said castings, bolts passing through said cross members "ed castings, a cage arranged between said upright members, a pneumatic hoisting mechanism fastened to said cross members, tracks fastened to the outer sides of the upright, members, counterweights traveling on tracks and connected to said cage, brackets fastened to one of said upright members and projecting outwardly therefrom, a transversely-extending member secured to said brackets, and a controlling device for said pneumatic hoisting mechanism mounted on the transversely-extending member.

In testimony whereof I hereunto affix my signature, in the presence of two witnesses, this 5th day of March, 1906.
